Unable to access the GUI after the fresh installation.

[Victor_Zing]

Hello Everyone, Good day!

I am new to Proxmox, installing it for the first time, successfully completed the installation on the DELL R710 server, apparently I am unable to access the GUI from my desktop. My Proxmox server is connected to my desktop via direct LAN cable (no router/switch in place).

Promox host file record entry by running the command - nano /etc/hosts/

127.0.0.1	Localhost.localdomain
10.1.0.111	Promox FQDN

Proxmox server network entries by running the command - nano etc/network/interfaces

Address	10.1.0.111/24
Gateway	10.1.0.1

My desktop (local LAN network details) -

Ipv4 address	10.1.0.12
Subnet mask	255.255.255.0
Default gateway	10.1.0.1

From the desktop, when I try the ping I get the error "Request timed out"
From the desktop, when I access the Proxmox GUI, I get the error "This site can't be reached"


Please note, I used the https along with the port :8006 while accessing the URL.
I turned off the windows firewall on my desktop, I read in the threads that Proxmox firewall service bydefault allows the traffic 8006 & 22 on local network. However, to eliminate that cause, I have also ran the command pve-firewall stop stopped the promox firewall service.

If you want me to run any command please share me the full command, for the reason I am also new to Linux realm. Thank you in advance.

What is the output of ip a (to check the connection)? What is the IP address of the desktop computer and your router (to check the local network)?

thank you for your super fast help.

As mentioned I don't have a router, the Proxmox server is directly connected to a standalone desktop via LAN cable.

If it's not connected to the router, then you probably want the desktop to be the gateway for Proxmox (10.1.0.12). Proxmox won't know how to reach 10.1.0.1 if its not connected directly. But this is not your immediate concern.

Some of the information is missing, but no-carrier is not a good sign. Are you sure the cable is connected to the right port (as there appear to be multiple).
Did you use a cross-cable? Most devices are auto-sensing these days but I don't know if that works with a PC to PC connection and/or Windows.
Maybe the network port on the desktop is not active? Do you see blinking lights on both computers?
You used a non-standard setup and connecting Proxmox to the router might be the easier fix.

Got you,

with regards to the cable - they are good, same cable works for connecting another PC's.
with regards to the local LAN port, I can see the green light on both the proxmox server & desktop.

will try to get a router and go with the standard setup and keep you posted - thank you so much @leesteken
